In 1913, the Nebraska Legislature acted to provide a Special Building Fund for the University  of Nebraska-Lincoln as an overdue acknowledgement of the University's horribly inadequate physical plant and grounds. Corresponding with the Special Building Fund was the first major campus expansion to the east across 12th street to 14th street, and from R to Vine. This land acquisition more than doubled the size of the original city campus, enlarging it to 37 acres (Logan-Peters).

In the spring of 1915, Bessey Hall was planned to be built shortly after Bessey's death in February of that same year. Although it is doubtful that Bessey was involved with the planning of this particular building, he had expressed interest in a new science building that the ideal laboratory would be oriented to the north, to take advantage of the soft northern light while using a microscope. Even before Bessey died, Chancellor Avery had expressed a desire to name a science building in his honor (Walsh).When the construction on Bessey was completed in 1916, it was already named Bessey Hall. This building was built in honor of one of the greatest                  professors in the University's history, and of course, in accordance with Bessey's wishes, laboratories were placed on the north side of the building. 

By the mid 1980's, Bessey Hall was starting to, quite honestly, fall apart. The building was a dreaded spot for undergraduate students, with its unairconditioned classrooms. Thankfully, in 1984 a major renovation was completed. In 1985 Bessey Hall was reopened. Even though the building was renovated, Bessey Hall still has many of its original features present today (Logan-Peters).

Throughout the years, Bessey Hall has been a key factor in improving the Sciences at UNL. Many different types of classes have been offered at Bessey Hall including Botany, Zoology, Astronomy, and many others (Bessey Hall Renovation). This building has been a characteristic of UNL for almost one hundred years, and it will always honor one of the greatest faculty members the University of Nebraska has ever seen (Sanders, 63-68).
